Commit errors for authors with name as display name

[jamessspanggg]

When clicking on ramp slices that are from authors with their name as display name rather than the GitHub user name, it leads to no commits found for this author.

For example, for the author Eugene Peh, all ramp slices link to: No commits found for "Eugene Peh".

(To replicate, run:
java -jar RepoSense.jar --repo https://github.com/reposense/RepoSense.git -i --view
, search for eugene and set granularity as commit)

Clicking all ramps of Eugene Peh links to this page:

Furthermore, it is shown in the image above that the author Eugene Peh has a commit "Restore functional test". But in GitHub it shows that it was the author with name eugenepeh that committed instead.

Lastly, there are repeated ramp slices that refers to the same commit:

(To replicate, using the same report as above, set since to 28/10/2018 and until to 16/11/2018)

Here's the link to the report

For further bugs in a self-generated report, please state the command and the version of RepoSense (if it is not latest master) you use to get the report, so we are able to reproduce it when reviewing it.

The error comes from here, we use git author name to be the GitHub id of Author.

But I guess there is no good fix for this. There is not enough information in git.
